SHIINGLE AND R005 IZEADE THEREFROM.

Application filed November 28, 192%. Serial No. 752,500.

This invention relates to a shingle and rooting and it is an object of this invention to provide a shingle adapted for the American method the open method of laying, and which is provided with a margin con sisting of a plurality oi? partially separated portions, one or more of which may be bent downwardly for supporting the same from when used as a gap-bridging shingle.

()ire of the objects of the invention to conform the exposed butt edges of the shingles to give the appearance of thicker shingles.

Another objec is to incline downwardly that portion of the butt edge of a superposed shingle overlying the gap between adjacent shingles. oi the course below so that said downwardly inclined edge will close the rap and prevent entrance of winddriven rain antsnow.

Another object is to downwardly incline an intermediate portion of the edge oi? the butt, on a straight transverse line thereby preventing the corners of the butt exposed end of the shingle "from cooking up.

Another object is to prevent entrance of wind under the shingle which tends to rip the shingles from the root.

The invention is disclosed in the novel structure and combinations hereinafter described and more particularly pointed out and defined in the appended claim,

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference runner-ale refer to similar features in the diitlerent views.

Figure 1 is a plan View of a roofing laid according to the open method.

are is a View similar to Figure 1 showing a rooting laid according; to the Ann-- eriean nethod.

.l igure 3 is an enlarged fragmentary sectional View upon the line IIL-III of Fig ure 2.

Figure 1 is an enlarged edge elevational view of the roofing shown in Figure 1 with. the lower layer of shingles omitted.

Figure 5 is a modification of Figure d showing; an L-shaped lap with the notches serving as guides in laying the shingles.

Referring to the drawings there is shown a shingle 1 having four V-shaped notches 2 in one margin. The opposite margin has a corresponding; nunrber of tits 01 tabs which from the shearing operation, and may be disregarded. These Vshaped notches define a plurality of partially separated portions therebetween. slits may be substituted ior notches and in the claim notches includes slits.

In the open method of laying shingles as shown in Figure 1 the two outermost notches or of each shingle which bridges the gap between other spaced shingles therebelow lie over the edges of such shingles as indicated at 3. The margin of the butt end of the shingle between said outern'iost notches bent or deflected downdiv on a straight line at the bend into rnent with the lower shingle and lies ,en the edges of the lower spaced lC-S as shown in Figures 1 and eland as a support for the butt end of the and closes the space between the l? the course below. The shingles are bly secured by nails or the like. *"gures 2 and 3 which illustrate the method or laying shingles, the t the upper shingles are closer in .-.l American spacing 0 than in the open method so that the two innermost notches of the gap-bridging shingles 1" lie between the edges of the lower spaced shingles as indicated at The margins of these shingles between the innerrnost notches are deflected or bent downwardly on a straight transverse line so that. the raw marginal edge will engage the lower sl ngle as shown in l igure 3, for support- M the bridging portion of the shingle against sagging and for closing the gap.

The v raped notches or slits are spaced according to the s 'izicing' of the desired shingles and therefore serve as guides in laying the shingles in addition to permitting: the intermec id'k} portions to be deflected downwardly. These deflected portions 1 and ('5 serve to support the intermediate or bridging portions of the gap-bridging; shingles and prevent gagging thereof which frequently produces leaking crevices.

l Vhen a shingle is allowed to sag at its mid portion, this operation cocks up the corners and gives the. appearance oi a warped shingle. The sagged shingle does not appear to be thicker than it is when Viewed from below but when the portion between the notches is bent down uniformly on a straight line, as described, the gap beloo tween adjacent shingles of the course below is entirely closed and an appearance of thickness of the shingle is presented.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles oi this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

A roof comprising a plurality of courses of shingles, each course embodying a plurality of initially fiat spaced shingles notched along their bottom edges, said notches registering with the side edges of shingles of a suhjacent course, the intervening portions of the superimposed shingles between said notches being hent downwardly on a straight line to :the depth of said notches JOHN A.
